Abstract: The invention relates to a process and a device for the high-speed flame-spraying of refractory filler materials in the form of wire and powder for the coating of surfaces, wherein, by means of at least two gas-mixing systems running independently of one another, the spraying filler material in the form of wire or powder, introduced into a primary combustion chamber, is fused by primary heating flames arranged concentrically around a charging channel, accelerated by the resulting high-speed flame and passed through a primary expansion nozzle bore into a downstream secondary combustion chamber, through which the primary high-speed flame passes at supersonic speed, taking along the melt-plastic filler materials, and which leads into a downstream water-cooled secondary expansion nozzle, axially widened centrically, or into the bore thereof, so that a zone of reduced pressure is generated in the region of secondary fuel gas/oxygen channels arranged radially, axially and/or in a focusing manner and leading into the secondary combustion chamber, and a fuel gas mixture can be fed at low inflow pressures and, in the secondary chamber, the fuel gas mixture is ignited and expanded radially, axially around the primary high-speed flame and, due to a high flame temperature and an extreme ignition and combustion rate, contributes to the final fusion of the spray filler materials and to their additional acceleration. <IMAGE>

Abstract: In a data transmission system with radio stations and devices remote from it, e.g. in a cellular mobile radio system, the radio stations transmit radio signals and receive radio signals which in each case contain data signals. According to the invention, as many as possible are shifted from the fixed stations to the remote devices for processing functions. The radio signal to be transmitted from the radio station (2) is generated by generating in the remote transmission device (10) an unmodulated carrier and a carrier modulated with the data signal, where the carriers differ in their frequency by the amount of the carrier frequency of the radio signal (f1). These two optical carriers are transmitted to the radio station (2), where they are mixed in an optical receiver to produce the radio signal containing the data signal. A radio signal which is received in a radio station (40) is optically transmitted to a remote device (44) and is further processed only when it is there. This transmission is carried out in that an optical transmitter (41) present in the remote transmission device (44) generates an unmodulated optical carrier and transmits it to an optical modulator (43) located in the radio station (40). In the optical modulator (43), the light, modulated with the received radio signal, is transmitted back and the radio signal (f1') is obtained by optical heterodyne reception of the unmodulated and the modulated carrier (v0', v1').

Abstract: 5 n7 An apparatus and method for controlling brushless DC motors are provided. Velocity loop control is performed digitally to produce current commands at a high frequency loop closure interval. Commutation of field coil current is controlled in response to current commutation pattern control signals produced in response to measured relative position of the motor rotor and motor stator and a velocity average over a number of loop closure intervals. Switch control signals to control transistor switches providing current from a DC power source to the motor terminals are produced in response to the current commands, measured motor current and the commutation pattern control signals. The velocity loop control implements a selected transfer function relating velocity, the motor torque constant, and the moment of inertia of the motor and associated load. Facilities are provided for periodically adjusting velocity loop transfer function gain factors and the effective moment of inertia in response to input signals. Additionally, current loop amplification gain factors and time constants are made selectable by input signals.

Abstract: 2.1 An inexpensive and relatively accurate digital/analog conversion is to be achieved, the tolerances of the small number of components used being insignificant in the determination of the measurement result. It should be possible to assemble the components necessary for carrying out the method in an integrated circuit which has low current consumption. 2.2 In a reference measuring phase, the number of counting steps is determined which are necessary for closing a switch so many times or for such a length of time until a capacitor is charged up to the value of the reference voltage. The number of steps thus determined forms the basis for a calculation, the number of steps of a counter being determined from the digital value to be converted, taking into consideration the digital maximum value and the divider ratio resulting from the reference voltage with respect to the maximum voltage, by means of which number of steps the switch then needs to be driven in a measuring phase for charging up the capacitor to the analog output voltage. 2.3 In the generation of the analog measurement variable, the tolerances of the currents and voltages needed for this and the tolerances of the components involved, for example capacitances and resistors of the components involved, are not included in the calculation. Since a reference measuring phase is in each case carried out immediately before a measuring phase, even changes in electrical values cannot have any influence on the magnitude of the analog output voltage. <IMAGE>

Abstract: In an image sensing apparatus comprising an array of image sensing elements, first and second shift registers are provided, each having stages divided into first and second sections, the stages of the first section of the first and second shift registers corresponding to odd-numbered elements and even-numbered numbered elements of the array, respectively. During each line scan, a transfer command pulse is generated to turn on gates to transfer image signals developed in the array to the corresponding stages of the first shift register of each shift register. A calibration sequence is stored into the second section of each shift register when the gates are in a turn-off state, and the shift registers are alternately driven to deliver the image signals followed immediately by the calibration sequences. The image signals delivered from the shift registers are combined to produce a complete video line signal. A difference in amplitude between the calibration sequences delivered respectively from the shift registers is detected for controlling amplitudes of subsequently delivered image signals.

Abstract: Magnetic resonance imaging methods for myocardial tagging are known for assessment of myocardial motion. In such methods tagging pulse and gradient sequences (tsq) are applied to the heart of an object (4) for acquiring tagged magnetic resonance images of, for example, heart slices from diastole to systole, the sequences being triggered upon detection of the R-wave of an ECG. With these known sequences, such as the so-called SPAMM sequence, it is very difficult, if at all possible, to automatically detect the tagging grid and therefore to evaluate the motion quantitatively. 
     According to the present invention, a magnetic resonance imaging method and device (1) are disclosed which allow for automatic quantitative motion evaluation of a part of an object (4). The pulse and gradient sequences (tsq) are applied in pairs with spatially differing tagging patterns, images corresponding to the pairs being subtracted so as to form a tagged image. The motion is monitored by scanning of the tagging pattern in the tagged image.

Abstract: The invention relates to an adapter plate for simple insertion in and removal from a conventional axial press. Using the adapter plate, an axial press is extended by use of wobble-pressing technology, so that both customary pressing methods can be carried out together in one axial press. The design features of the adapter plate are based on complete separation of the drive assembly for the wobble press by the adapter plate. In this way, both pressing methods can be used together even where it has previously been necessary to forego one of the two pressing techniques, mainly because of the high investment costs. <IMAGE>
